What proportion of mobile phone users can access the web through it?

How can I trigger an event in a web app when one of my users receives an SMS?

  • Details: All my users are located in the US. It's a text message to their personal cell number.  I do not own the number. I can have them do any sort of verification needed (respond to an SMS from a carrier, let's say), but I do not have physical access to their phone, so it must be a simple process, if I'm going to have them do it remotely. I need this event to be triggered instantaneously, even if their cell phone is off (which rules out creating any sort of app on their phone, I believe.) Answers that are applicable only to one or more specific carriers are welcome.

  • Answer:

    There are many Tools online that will allow you to send out Text Messages and receive delivery reports and if required responses. I used to work for a company called TextLocal and I know we had an API that would contact your server with a POST request when a message was delivered, read and replied to. This may be an option for you.

If you send the sms throght a smpp or some API third service provider you can define that notification about the status of the sms (deliver, queue, recibed etc), you can also receive the deliver if you send the sms throght a cell modem if you define this request before send it and if the receiver allow that notification Keep in mind that if the receiver have turn off his phone, it wont be a notification of the deliver, because the smsc of the carrier is waiting that the phone register in the network again in order to deliver this sms, if the phone wont turn on in a windows time define by the carrier (maybe 24 hour) the smsc will discart the sms and you wont receive any deliver status if this timeout occur
